There's no reason they couldn't have released the wallet immediately after the fork. After all, they need a wallet to be mining it themselves. But hey, they get all this time to solo mine it and then we all get to watch "you're a scammer cause you mined it when no one else could" posts. So that will be entertaining. Usually, coins like this get pump and dumped and then fade off into nothing with just the bag holders trying to keep it alive. Followed by the community take over and continued limping. Only thing that would keep it from dying off quickly is that it's POW and not POS.
